Anyone on the group any suggestions on the following couple of probs I'm having with my 97 740I.

When cruise is engaged, the car without warning will surge forward under acceleration then just as quickly decelerate. It may do this a couple of times in succession and then the cruise control will disengage itself, for safety reasons I guess. At other times the cruise works just perfectly.

When locking the car with the remote and thereby setting the alarm. The car used to make the "chirping" noise. All on its own it stopped doing it when the alarm was set or turned off.

The alarm has also started going off without warning, all the windows and the moonroof are fully closed. The turn signals and lights flash but there is no horn, the horn works OK though. If I press the "panic" button on the remote again the lights will flash but there is no horn.

Is there anything that I should check, fuses, ECU's wiring connectors etc that may be causing this. I've only just got the car and I don't have a shop manual yet.

thanks in advance.
